Mechanic's Mistake Trashes $244 Million Aircraft
Hugh Pickens writes "An accident report is finally out for the Air Force E-8C Joint Surveillance Targeting and Attack Radar System that had started refueling with a KC-135 on on March 13, 2009 when the crew heard a 'loud bang throughout the midsection of the aircraft.' Vapor and fuel started pouring out of the JSTARS from 'at least two holes in the left wing just inboard of the number two engine.' The pilot immediately brought the jet back to its base in Qatar where mechanics found the number two main fuel tank had been ruptured, 'causing extensive damage to the wing of the aircraft.' How extensive? 25 million dollars worth of extensive. What caused this potentially fatal and incredibly expensive accident to one of the United States' biggest spy planes? According to the USAF accident report, a contractor accidentally left a plug in one of the fuel tank's relief vents (PDF) during routine maintenance. 'The PDM subcontractor employed ineffective tool control measures,' reads the report. Tool control measures? 'You know, the absolutely basic practice of accounting for the exact location of every tool that is used to work on an airplane once that work is finished.' Air Force Chief of Staff Gen. Norton Schwartz just told Congress, 'there is a JSTARS platform that was damaged beyond economical repair that we will not repair.' So, if this is the one Schwartz is talking about, then one mechanic's mistake has damaged a $244 million aircraft beyond repair."
I've been an A&P for over 35 years and I've seen worse.

You've hit the nail on the head with #1 - #3. They totalled a 707 airframe, which is not a $244 million dollar plane. Most of that $244 million cost is what makes a 707 a JSTARS -- the payload. And the payload will probably be salvaged and re-used either to build another JSTARS or as spares to support the existing JSTARS platforms. This is being way over-hyped. Big oops for the contractor -- I wouldn't renew the contract; but, I'm not government.
There are a lot of misconceptions about how contractors work, because typically, their profit margins are no higher than in other lines of business.
The government is big on COTS hardware/software, and only turn to contractors for specialized circumstances. Those extra zeros come from the unusual design requirements and low volume orders.
Take the x thousand dollar hammer example. On the surface, that seems absurd, since one can buy a hammer for less than 10$. But when the hammer is going into space and is made of a difficult to machine titanium alloy (tool steel shatters at cold temperatures), is egonomic even through spacesuit gloves, is lightened without reducing mechanical efficiency (makes sense at an estimated 1000$/pound/launch), and only 10 are made (despite flat machining costs), that X or XX thousand dollar price tag seems very affordable.
The same thing happens in other areas. I work on submarines and some components use joysticks. Sure, commercial joysticks can be obtained for under 100$, but a waterproofed, pov only motion, high durability (sailors treat equipment like crap, and failure is not an option) piece of clockwork machinery that maybe 50 will be made, you are looking at just shy of XX thousand per.
